Close #15908

Hi @sachelsout, thank you for your contribution ! However, I think there's a mismatch between your implementation and the To-Do list in which you added your issue. You are implementing the paddle.tensor.math.atanh frontend function but the To-Do list linked to your issue concerns instance methods located in the paddle.tensor.tensor.Tensor class.

The function you currently implement is already being worked on in this issue so I suggest you make another PR where you implement the instance method as explained in the To-Do list. Otherwise feel free to work on another function but make sure you reference the appropriate list, thanks !

Hi @nassimberrada, apologies on my end, I executed atanh function (tensor.math) for tensor.tensor related issue. Thank you for explaining in brief. 😊
I have a doubt though. There's an issue #15802 for adding asin function in tensor.tensor related issues but the person has executed asin for tensor.math related issue in math.py.
Could you please let me know if I'm missing something.

Thank you.

Thank you.

No worries ! My guess would be that there was a mistake there because there's a separate To-Do list for paddle.tensor.math function here. There is an on-going issue for asin in that list but as you can see the PR linked to that issue was closed because the function was already implemented. Hope this makes sense !

Thank you for the clarification 😊 Much appreciated 👍🏻
